Hi everyone, I’ve an old Komatsu PC20 (or FAI 232) Triple Gear pump and rexroth control valve. It has bucket in/out problems. I’ve checked the pilot pressure, low rpm engine, 10bar, when you do every other movement it goes up till 30bar but doing bucket stay still on 10, if you do combined movement it goes perfectly. I’ve checked the spool but It moves fine I’ve tried to switch p1 with p2 to see if something changes but nothing.
